摘要：
The electronic structures and magnetic properties of two dimensional (2D) hexagonal Ni(OH)2 are explored based on first-principles calculations. The results reveal that the ground state of the pristine Ni(OH)2 is a direct semiconductor with antiferromagnetic (AFM) coupling between two nearest Ni atoms. Interestingly, the monolayer Ni(OH)2 becomes a ferromagnetic (FM) semiconductor under a biaxial compressive strain of 4%. Furthermore, the band gap of monolayer Ni(OH)2 can be modulated by the different biaxial strains. These tunable electronic s...
